IT will be two expensive an them callin giot a pocket shot gun will onkly bring more attention to 45 . 410 pistols .

you can build a single shot like that for about $50 with jack squat side plates an a derringer kit .

this company is not cheap . I kind of like the idea of a big bore derringer thats light an thin for concealed carry I think it would be a good purse gun an with buck shot or a 410 slug its going to leave a mark .

Those large-caliber Derringers are one-shot wonders. Great for self defense but your hand will feel every shot for a few days! I would personally use it in .45 Colt vs. the shotshell idea but that's me.
